Matlab please answer all the questions

Question 1: Write a script for drawing the following curve using the surf function. f(x, y) =-er-er-16 The range of x and y values are read from the user. Label the axis and give the diagram a title. Color the curve in red. Test your code for-5 Sx s 5 and-5Sys 5 Question 2: Write a script to generate a square matrix such that the elements of each row of the matrix consists of sequential numbers. For example, if n = 3, the matrix is: 1 2 3 4 5 6 Question 3: Create a function, called MT, which takes as an argument two matrices. Both matrices are of size (1XN). Let the matrices be x and y. The output of the function contains two items. First is the product of xy and the second is yaT. Note: x is the transpose of the matrix x Question 4: Create grid coordinates from x, y defined in the interval [-1,1], and evaluate the expression
